Explanation:
Bases taste bitter, feel slippery, and conduct electricity when dissolved in water. Indicator compounds such as litmus can be used to detect bases. Bases turn red litmus paper blue. The strength of bases is measured on the pH scale.
<span>An element with 1 valence electron has a charge of -1, because there is an extra negatively charged electron attached to the ion.</span>
Answer:
The current in a resistor decreases by a factor of 4.
Explanation:
I = 
Where (I) is the current, (E) is the voltage and (R) is the resistance.
Decreasing the voltage by 4 gives;
I = 0.25
Since you have multiplied by 0.25,
You have to multiply I by 0.25 so the current decreases by a factor of 4.
It is true that scientists use mathematical models and satellites to test theories about the universe.
Mathematical models are usually quite precise and help these scientists test theories that may otherwise be untestable without the help of mathematics. Scientists use many models and satellites to help them , but mathematical ones are probably the most important.
Answer:
Area = 648.9 m²
Explanation:
Given that, the radius of the circle = 14.37 m
The formula for the area of the circle is shown below:
Thus, applying the values in the above formula as ;
<u>Area = 648.9 m²</u>
